I'm surprised 3DS ever went at the top. But if any time makes sense, around 2013 adds up.
Animal Crossing: New Leaf, A Link Between Worlds and Pokemon Gen X/Y were released that year. Also, you had a build-up of titles already like Super Mario 3D Land and Mario Kart 7.
The Game Boy was lumping the GB and GBC together (as Nintendo does). Individually, neither would probably be the best-selling in 1999 or 2000.
The Xbox 360 was clearly relying on Kinect and different price options. The Wii was declining sharply by then and PS3 wasn't ever as popular in the US.
NES, PS4, and Switch have the longest streaks. 5 years for each of those Nintendo platforms and 4 (ha) for the PS4. DS and Wii were close in 2008, so the DS narrowly missed a 5-year streak.
Lifetime Sales Predictions
Switch: 161 million (was 73 million, then 96 million, then 113 million, then 125 million, then 144 million, then 151 million, then 156 million)
PS5: 122 million (was 105 million, then 115 million) Xbox Series X/S: 38 million (was 60 million, then 67 million, then 57 million. then 48 million. then 40 million)
Switch 2: 120 million (was 116 million)
PS4: 120 mil (was 100 then 130 million, then 122 million) Xbox One: 51 mil (was 50 then 55 mil)
3DS: 75.5 mil (was 73, then 77 million)
